Camera Translation/Rotation

Moving on the axis's is fine and dandy, and so is rotating the view of the camera.
Combining the two so that I always move in the direction I am viewing however, I'm rather confused with.
This is my (pseudo)code:
Any simplistic suggestions?

Rotation prior to translation still results in my having the issue of only moving along the x or z axis. It just gives me the lovely view of the direction I'd like to be moving in as I do so.
Your camera's position is in world coordinats, so forward isn't always going to be along the x axis. You have to figure out which way forward is and move in that direction instead.
`TranslationCamera.Move(vForward * distance)
this is part of my camera class.
then just update our view matrix
with something like
void CCamera::MoveCamera(float Speed){ // Get vVector: Direction camera is facing D3DXVECTOR3 vVector = m_vView - m_vPosition; D3DXVec3Normalize(&vVector,&vVector); // Move camera along the vVector m_vPosition.x += vVector.x * Speed; m_vPosition.z += vVector.z * Speed; m_vView.x += vVector.x * Speed; m_vView.z += vVector.z * Speed; }then just update our view matrix
with something like
D3DXMATRIX CCamera::Look(){ D3DXVECTOR3 position(m_vPosition.x, m_vPosition.y, m_vPosition.z); D3DXVECTOR3 target(m_vView.x, m_vView.y, m_vView.z); D3DXVECTOR3 up(m_vUpVector.x, m_vUpVector.y, m_vUpVector.z); // cameras view matrix D3DXMATRIX V; D3DXMatrixLookAtLH(&V, &position, &target, &up); return V;}This topic is closed to new replies.
